Back in January 2015, the founder of Cyanogen - Steve Kondik said that they will be releasing their new mod, the Cyanogen 12 which is based on the Android 5.0 lollipop by the first week of March enabling devices such as their 'partnership' device OnePlus One, which is likely to receive their first update.
OnePlus One, more than its appreciable hardware, is known for its patch up with CyanogenMod. Unlike other Androids, it runs a heavily customized and popular mod which is based on the android kernel to give it a rich and an exotic user experience and yet stands apart from the regular android.

The Oxygen OS

But along with the CyanogenMod 12 update, It will also unveil it's OXYGEN OS, which is also Android based, but proprietary made by the young devs over at OnePlus. While there's not much light shed on its new OS but it has sure has startled the current users and even us, switching from CyanogenMod to a completely new Oxygen OS can be a risky step for the company.
The reason given by the team is quite straight, they wanted a better localization and faster updates with an OS which is totally designed as per the hardware of their devices. Just like the iOS. The logo of their OS gives off a striking resemblance to their brand logo as "these designs represent the harmony between hardware and software" as coined by their team.
While the world is eagerly looking forward to see OnePlus to release its TWO, This update could give it a prestigious finish to the series and mark the start of the journey of the OnePlus Two, with Oxygen OS.
